To all whom it may concern.

Be it known that we, GEORGE W. K ne, HARRY J. BARNHART, and .OHARLEs B. KING, citizens of the United States, residing at Marion, in the county of Marion and State of Ohio, have invented certain new and use mprovements in Steam-Shovels and the Like, of which the following is a specificatio'n, reference being had therein to the accom anying drawings.

TllS invention relates to steam shovels and the like, and more particularly to the means whereby they are propelled and guided.

' The'main object of our resent invention is shall be adapted for use on ordinary roadways or surfaces other thanrailways, bei'n capable, "however, of being readily mounted on the railway trucks usually employed when the apparatus is to be used in connection with a railway, and being adapted to be self-propelling in either case, provision bein made for read1ly guiding the same when used elsewhere than on said railways. i

To the above endsour invention consists in certain novel features which we will now proceed to describe, and will then. particularly point outin the claims.

In the accompanying drawings, Figure 1 is a side elevation of a steam shovel having our mprovements applied thereto, in one form,

Fig. 2 is a plan view of the same; Fig. 3 is a vertical sectional view on an enlarged scale, illustrating the transmission of t from the main engine-shaft to the sprocket chains Fig. 4 is a plan view, of the propelling shaft and counter-shaft, and the gearing thereon; Fig. 5 is a detail plan view of a portion of the rear end of the machine, partly broken away, and illustrating thestcering devices; Fig. 6 is a vertical sectional view of the same; big. 7 is. a longitudinal sectional view, taken centrally throughthe forward part of the machine, showing the same mounted on ordinary railway trucks; Fig. 8 is a transverse sectional view, showing the front railway truck in elevation,:-with the jacks in position for removing the same and Fig. 9 is a transverse sectional view, showing the rear truck in elevation.

In the accompanying drawings, we have shown our invention as applied to a steam shovel, although it is obviously applicable to other machines, of the same general charace power ter, and is shown as equipped for use 11 on the surface of the soil or upon any 0t er suitable roadway or surface not a railway.

1 indicates the body usual boiler 2 and engines 3 thereon.

a pinion 5 which meshes with ,a gear 6 on the mam or hoisting drum shaft. This shaft gear 9 on the propelling shaft 10. These parts are common to most structures of this class, and may be of any approved construction, The gear 9 has secured to it a sleeve 11,

which is provided wit a clutch member 12.

. 13 indicates an elongated pinion mounted loosely on the shaft 10, so as to slide freely longitudinally thereof, and rovided with a clutch memberla adapted to engage the clutch member-12. Said clutch pinion 13 is provided with a groove 15 in its hub to re 'responding' front wheel of the machine, the

is secured to the'c'arbody by the same bolts struction that themachinemay be readily, mountedon such trucks by removing the the counter-shaft .12} and the gear, and

'55 and side bearinlg1 in position and t 10 in place of the pinion 13 and a sprocket chain 59 extends about said sprocket sheave and about either of the sprocket wheels 6 and 61 on the axlesof the front and re trucks, respectively, and the structure is than. propelled. the. usualj wtty. The tractio or frame, having the which is keyed on the ropelling shaft 10, and

ceive the .usual trunnion collar to which the each sprocket wheel "19, there passes a sprocket chain 20, which extends to the cor front wheels being the driving-wheels, and rovided. with sprocket-wheels by. jv'hic t ey 'ajre driven. The front axle, 2.1,

4 indicates the main engine-shaft,havin'g also carries a gear 8, which meshes with a that hold the", centenplate and side bearings, in place when the machine is mounted upon}, railway trucks, and it 'resultsfrom this con-- front axle and its wheels, the sprocket chains,

sprocket ewheels carried thereby',-- and the fl". clutch pinion 13. The center bearingjplatje plates 56 are then placed; e ordinary railway truck 57 mounted thereon. The usual sprocketi; sheave 58 is mounted on the propelling shaft.

drivin wheels are indicated as a whole by the reference numeral 22 and their sprocket wheels by the reference numeral 23, and are mounted to turn on journals on the ends of the non-rotatin axle 21.

The steering is effected, when the machine of the car and having its shaft 28 connected with a steering shaft 29 by means of any suitable gearing, that which we prefer being a sprocliet-wheel 30 on the engine-shaft 28,

' and a sprocket-wheel 31- on the steering shaft shaft in the other direction. inner end of the steering shaft is connected 29, the two connected by a sprocket chain 32. The steering shaft 29 is mounted in a bearing box 33 secured to the underside of the car body 1, and the. hub of the sprocket-.

wheel 31 bears against said boxat oneend, so as to prevent longitudinal motion of the shaft in one direction. 'A collar 34 on the shaft '29 bears against the other end of thebox and prevents longitudinal motionof the by a universal joint 35 to a sleeve nut 36, and this sleeve nut has threaded into it a screw shaft 87, which is connected by a universal joint 38 to a clamp or clip 39, secured to the axle 25 at one side of its central pivot. By

" reason of this connection between the steering shaft 29 and axle 25, rotary movement may be imparted to the sleeve nut in either direction, and such. rotation will move the screw shaft either forward or backward, as

the case may be, and will swing the axle around its pivot in either direction. The universal joints allow the connecting parts to accommodate themselves to the varying positions of the axle and permit free rotation of the sleeve nut. The engine 27 is reversible, and through it the necessary power is obtained to readily rotate the steering shaft in either direction, thus making it possible to steer the machine with great nicety without calling for any muscular exertion on the part of the operator.

, It will be seen that the machine can be readily mounted on railway trucks, so as to be drawn or propel itself along the railway track, and that it may be readily adapted for use on surfaces or roads elsewhere than'on railway tracks by removing the railway trucks and applying the axles and ground wheels shown in the accompanying drawings. The change in the propellin mechanism to conform to this change in t e wheels can be readily and quickly made, and the steering mechanism is such as to give a ready and complete control of the guiding of the machine.

The front or.

' or connecting said drivin We do hot wish to be understood as limiting ourselves to the precise details of con struction'hereinbefore described and shown in the accom anying drawings, since these details may 9 viously be modified without departing from the principle of our invention. Q
